HAL_Delay running too fast in STM32N6 Application with TIM2 timebase
Hi all,I've created a new default project for the STM32N6 Discovery Kit, and set up a simple blinking application using the BSP LED functions. /* USER CODE BEGIN 2 */ BSP_LED_Init(LED_GREEN); while(1) { HAL_Delay(1000); BSP_LED_Toggle(LE...
STM32F051 Internal comparator configuration
Hi,I am trying to configure the internal cooperators in the STM32F051 micro-controller, but in the .ioc file I am able to configure only one Comparator. I require three comparators for my application. Is it possible to configure multiple comparators ...
Resolved! Can I implement a nanosecond delayed signal output with the stm32H723 chip
I would like to implement delay signal output with STM32 MCU.So I use the original signal input for EXT interrupt.EXT interrupt's callback activates the timerIf a timer callback is called after a time delay of the desired value, it is implemented by ...
STM32H5 Flash layout obk and sytem
Is there a comprehensive single documentation source of the Flash layout for say, an STM32H563?The documentation I find is very opaque. Questions I have at present (From a non secure perspective):1. Where is OBK located? (0x0BF0000 to 0x0BF9FFFF ???...
800 x 800 Display with STM32U5G9VJT6Q - possible?
Hi,we are trying to get a 800x800 display to work with the STM32U5G9VJT6Q, using either RGB888 or RGB565 in Video Mode (Burst).According to what we read it is definitely possible. Did we miss something?Could someone please confirm that is definitely ...
I2S clock soruce - internal MSI RC or external HSE ?
I am using I2S (SAI) on the STM32L433 nucleo board and using the internal MSI RC as the clock source.I also have a 32.768kHz LSE external crystral which I believe helps to make the MSI RC clock more accurate when used with PLL.Is the internal MSI RC ...
VCORE supply configuration on STM32H755XIH6 and MEM corruption correlation
Hi, I am using an STM32H755XIH6 MCU in a custom design. I want to use only LDO supply configuration for the internal power regulator that provides the VCORE and I don't really intend to use the SMPS configuration. My schematic has some hardware mista...
Choosing Internal vs external Clock
I do a project with the newer STM32 G , C series and i am curious what are the benefits of external clock vs using the internal clock, because it will save cost and layout space ?
